Diet pill alli (low-dose orlistat), which earlier this month became the first FDA-approved over-the-counter diet drug, may ultimately be available in countries around the world.

Roche, which sells the prescription version of orlistat called Xenical, announced on Feb. 20th that it had granted GlaxoSmithKline an exclusive license to sell the half-strength version in countries outside the U.S. and Japan.

Roche had licensed the U.S. nonprescription rights to Glaxo in 2004.

Roche said it will retain all rights for the prescription version and will continue to market Xenical worldwide.

alli, which reduces the amount of fat the body absorbs from food, was approved by the FDA for use by overweight adults in combination with a reduced-calorie, low-fat diet and exercise.

Glaxo expects to have it on supermarket and drugstore shelves sometime in the summer.
